Balanced Three-Phase Power Measurement Connection - Fluke 345 User Manual

Carefully observe the direction of the current flow on the top of the
Clamp Meter.
Always adhere to the instructions regarding the sequence of
connection.

Balanced Three-Phase Power Measurement Connection

In three-phase power networks where the load may be considered to be
balanced, the Clamp Meter may be used to make some basic measurements
such as watts, VA, PF, and kWHr.
This measurement is only suitable for balanced loads. It is not
suitable for measurements other than nominally balanced, due to the
consideration of only one current phase.
Current is measured on one phase and the two voltages are measured on the
remaining phase.
Figure 9 shows the three-phase setup screen for the balanced three-phase
power measurement.
